Microsoft issued a patch for its supported systems in March, weeks before Shadow Brokers released the exploit, but many computer systems around the world remained unpatched, leaving them vulnerable to the latest ransomware attack. The WanaKiwi tool works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008 operating systems like the WannaKey , and can run using the command prompt.
The National Cyber Security Centre has created a guide on how to deploy these patches. Wanna Cry spreads over networks so if even one computer is affected, the rest on the network can also be compromised. On Sunday, Chinese media reported that students at several universities were hit by the virus, which blocked access to their thesis papers and their dissertation presentations.
But Raymond James analysts Aaron Kessler, Justin Patterson and James Pardee upped the ante, writing Thursday that they were impressed with Alibaba fourth-quarter results, which missed analyst estimates by a penny per share. Alibaba has expanded into new areas in response to the deceleration, buying control of Lazada Group SA to gain a Southeast Asian foothold and waging a price-based war with Tencent Holdings Ltd.in cloud computing services.
China wants to put ties with South Korea back on a "normal track", President Xi Jinping said on Friday, but Beijing also urged Seoul to respect its concerns and resolve tensions over the deployment of a US anti-missile system that it opposes.
Windows XP was one of the versions of Windows to be affected by the WannaCry ransomware attack, and despite the patch released by Microsoft , there were still thousands of computers which ended by being affected. However, the respective central banks at the two countries have issued statements to minimise any concern that banks have been affected by the ransomware attacks.
Now that this "WannaCry" malware is out there, the world's computer systems are vulnerable to a degree they haven't been before, unless people everywhere move quickly to install Microsoft's security patches . Cyber security experts say the spread of the virus dubbed WannaCry - "ransomware" which locked up computers in vehicle factories, hospitals, shops and schools in several countries - has slowed, but that any respite might be brief.
